My gf is like a 9/10 and from a conservative home. Many would think Ive won at life, but the s** she had before we met is killing me.

Basically she and her sister went on a camping trip with their family. They were bored and started wandering the area, until they were invited in to a random house. The guy there gave them a drink and then asked if they wanted to f***. They told him sure.

So yeah. He got two virgin pussies and two sisters. He did them while they leaned over the table in the living room, and after he made sure they got the pill.

So basically he had like every guys fantasy completely randomly. I have a very, very hard time accepting it happened. Our relationship is great other than that. How can I deal with this?
